Description

The present invention relates to a hygiene product

  adhesive associated with a "service bag" intended to contain a

  identical duit used. These hygiene products may be, in particular, periodic towels or dressings.

  It is known that periodical napkins intended to ab-

  sorb menstrual flows are often provided, on their face which is intended to come with respect to a female undergarment, of at least one school stroke, continuous or discontinuous, rectilinear or not, intended to ensure the The adhesive product, which is thus associated with the napkin 9, must, of course, be protected from storage by means of a potect on, which is the

Although the parnters are not affiliated with any of them, they are not associated with any of them. 3 per cent and 4 per cent of the $ 3 per cent of the total amount of service to be used to pay for the US $ 8 per day. 'ounure the price die

  comes back from a hygiene product of the type indicated above,

  marketed in association with a service bag. According to the

  vention, the idea of replacing the protective element

  the adhesive product of the hygiene product, by the sachet-

  service itself, which eliminates the cost of the protection element in the overall cost price. It's clear

  whereas, in these circumstances, the constituent material of the sachet

  service must necessarily satisfy a certain number of

  peratives. In the first place, the constituent material of the sachet

  service must be able to weld on itself so that from a tubular band, it is possible to form by welding the bottom of a

  bag but it should not weld on the nonwoven material

  positioning the outside of the hygiene product, so that the welding of the ends of the service bag does not achieve the fastening of said bag with the hygiene product. Secondly, in the case of periodic napkins, the material constituting the service bag must allow the transfer of an adhesive product on the nonwoven material, which is constituted by the outside of the

  towel, if one wishes to maintain the general characteristics

  rays of the previous manufacture, that is to say deposit the col-

  the on the protective element and then transfer this glue from

  the protective element on the towel.

  The hygiene product according to the invention can

  generally be manufactured using the same manufacturing processes

  the hygiene products of the state of the art.

  In the case of periodic napkins, the hygiene product is manufactured in the form of a continuous strip, which is cut to the desired length by thermo-welding the ends. According to the invention, it is unrolled vertically

  of the band intended to form the periodic napkins

  tubular element folded flat and consisting of a sheet of

  appropriate material, this continuous tubular element being welded and

  cut to the same length as the towel by the operation of

  thermo-welding and cutting the napkin itself. The the-

  tubular cut thus constitutes the service bag and, at the same time, the protective element of the adhesive product, which is

  transferred from said tubular member to the shaped nonwoven material

  the outer sheet of the periodic towel.

  The subject of the present invention is therefore the new industrial product which constitutes a hygiene product, one side of which absorbs body fluids and one of which

  comprises an adhesive product, said adhesive product being coated

  green of a removable protective element, characterized in that the protective element is a flexible tubular element folded flat, substantially of the same length as the hyogenetic product and closed at at least one of its ends, the cross-section of the unfolded tubular element being greater than the

  cross section of the hygiene product.

  In a preferred embodiment, the tubular element

  it is closed at both ends and has, in the vicinity of one of its extremities, a line of weak resistance; the

  line of weak resistance is a dotted line constituting a-

  tears; the tubular element consists of a thin sheet welded on one of its generatrices and at both ends; the tubular element is folded flat, so as to

  have two faces parallel to the mean plane of the product of hy-

  These two faces are interconnected on each of their longitudinal edges by a V-fold, the tip of the V being directed towards the central zone of the hygiene product; the constituent sheet of the tubular element is made of a material taken from the group formed by lacquered polypropylene or coated silicone paper, towards the inside of the tube, of a

  binder layer weldable on itself.

  In a first variant, the hygiene product is a periodic towel whose face which absorbs body fluids is opposite to the face which carries the adhesive product; the adhesive product is disposed between the absorbent element of the

  towel and the tubular element, according to at least one line

  it runs parallel to the axis of the napkin.

  In a second variant, the hygiene product is

  an adhesive bandage with a face that absorbs the cor-

  porels and the same one that bears the adhesive product; the

  adhesive product is apparent at the periphery of the absorbent

  bant of the dressing and the tubular element covers both the

  adhesive product and the absorbent element.

  The present invention also relates to a method of

  de nufacture of a periodic towel of the type defined above, wherein is produced a continuous strip intended to constitute the absorbent element of the periodic towel, this

  process being characterized by the fact that

  one of the faces vis-à-vis the tubular elements and absorbs

  along the axis of this face, an appropriate adhesive product

  prayed; that the tubular element is applied to the ab-

  sorbent to cause the gluing of the two elements one on the other; that we heat weld and that we cut in

  the welding zone, on the one hand, the absorbing element of the

  on the other hand, the tubular element, the

  mant-each of the two elements but do not weld them together,

  the welding-cutting taking place on the continuous strip at inter-

  regular valles equal to the length of the napkin.

  In a preferred embodiment of the process according to the invention, the adhesive product is deposited on the tubular element,

  the application of the tubular element to the absorbent element

  voiding the transfer of the adhesive product on the absorbent element; at the same time as the welding of one end of the napkin, a low resistance transverse line constituting a tearing primer is produced on the tubular element, these low resistance transverse lines may also, in a variant, be produced at regular intervals during the manufacture of the tubular element, before its association with

the hygiene product.

  In a variant embodiment, the hygiene product can be produced in the form of a continuous strip comprising a succession of identical hygiene products connected to each other by separation zones that the user cuts to separate from said continuous strip. the hygiene product of which

he needs.

  It is clear that the hygiene product according to the invention makes it possible to economize on a protective element distinct from the tubular element intended to constitute the service bag.

  the invention can be carried out continuously, as for the corresponding hygiene products of the state of the art, without significant modification of the production machinery. In addition, in the case of periodical napkins, the conditioning of the

  towel and its associated service bag is easily

  multi-layer complex, which allows absorption and retention of

  menstrual fluid and is covered externally--

  a non-woven sheet. On the face of the service

  viette, which is intended to come into contact with the underwear

  of the user, the absorbent element 1 carries a line

  of adhesive product 2 disposed along the longitudinal axis of the

  absorbent element and having a width of 35 mm. The face of the

  the absorbent element 1, which carries the adhesive product 2, is

  green of a service bag designated by 3 as a whole.

  The bag 3 is a tubular element folded flat cons

  staggered with two faces 3a> 3b parallel to the mean plane of the

  the absorbent element 1, interconnected by V-shaped folds 3c arranged along the longitudinal edges of the tubular element 3. The tip of the V, which constitutes each fold 3c, is directed towards the axis of the tubular element 3 and the width of the tubular element 3 folded is slightly less than the width of the absorbent element 1. The tubular element 3 is made from a lacquered polypropylene sheet, which has been folded flat suitably and welded along a generatrix of the tubular element, the weld being visible

  in Figure 4, where it has been designated 4.

  The manufacture of the napkin, which has just been described, is carried out on conventional machines, which make it possible to obtain periodic napkins continuously. A continuous strip is manufactured containing all the constituent elements of the absorbent element 1 and is brought, in line with this continuous strip, a continuous strip constituted by the tubular element folded flat 3. It is deposited on the face of the tubular element 3, which is opposite the absorbent element 1, a line of adhesive product and the tubular element 3 is applied to the absorbent element 1 thus realizing the transfer of the adhesive product on the absorbent element to obtain the adhesive line 2. The adhesive product is a self-adhesive adhesive of the type of adhesive

  those which are already conventionally used for this

in the state of the art.

  When a continuous band formed by the superposition of the constituent strip of the elements 1 has thus been formed.

  and the constituent strip of the tubular elements 3,

  gives rise to a thermo-welding operation at regular intervals

  guliers on the continuous strip, the distance between two welds

  successive lengths corresponding to the length of a towel

  periodical. The heat-sealing performed allows the ends of the absorbent element 1 to be welded together and at the same time the ends 5 of the tubular element 3, which is associated with the absorbent element 1 of a towel, to be welded together. However, the choice of the constituent material of the tubular element 3 makes it possible to obtain the thermo-welding of the walls of the element

  tubular on themselves but avoids the thermo-welding

  3 of the tubular element 3 on the ends 1a of the absorbent element 1. At the same time as the weld, a cut is made in the central zone of the thermo-weld, which makes it possible to

  cut the continuous band to obtain the towels

  periodicals. Furthermore, at the same time as the heat-sealing of the ends 5 and 1a, on the tubular element 3 a

  tear line 6, constituted for example by perforations

dotted lines.

  The user, who comes out of his conditioning a service

  periodically according to the invention, takes off by simple trac-

  the tubular element 3 and separates it from the absorbent element 1. It then tears the element 3 according to the dotted line 6, which makes it possible to open one of the ends of the tubular element 3 which then constitutes a sachet . The user spreads the folds 3c, which constitute bellows, to give the bag the

  maximum section and place in this bag the towel

  used that it wishes to replace. Then she sets up the new periodic towel, the line of adhesive product 2 for maintaining said towel with respect to the

underwear of the user.

  It can therefore be seen that the napkin according to the invention makes it possible to economize on a separate protective element of the service bag, which constitutes the tubular element 3. In addition, the manufacturing method according to the invention makes it possible to get the new towel periodic using the machines of

  production of the state of the art with very small

  essentially relating to the production and

  introduction of the tubular element 3.

  It is understood that the embodiment described above is in no way limiting and may give rise to all

  desirable modifications, without departing from the framework of the

vention.
